      “On this preliminary record, we agree with Patent Owner that Petitioner’s asserted level of ordinary skill in the art is higher than warranted when Petitioner argues that a person of ordinary skill “further would have had specific experience with implementing and designing library preparation methods.” Pet. 21–22. However, we disagree with Patent Owner that a POSA only need to “have had experience with DNA sequencing methods” (Prelim. Resp. 8) because an artisan with experience with only pre-NGS sequencing methods would not qualify as a person of ordinary skill. Instead, for purposes of this Decision, we find a person of ordinary skill would have had a Ph.D. in the field of chemistry, molecular biology, or biochemistry. Alternatively, a POSA would have had a B.S. or M.S. degree with three to five years of experience working in any of those fields. The person of ordinary skill would have had experience with NGS sequencing methods and a working knowledge of how those methods functioned. This definition of a person of ordinary skill is consistent with the skill level reflected in the disclosures of the ’357 patent and prior art. We further note that neither aspect of the dispute over the skill level affects our decision to institute review.” slip op. at 9

      “1. “indexing site” Petitioner argues that the ’399 patent defines “indexing site” as a sample index, specifically, “a nucleic acid sequence that acts as an index for multiple polynucleotide samples, thus allowing for the samples to be pooled together into a single sequencing run, which is known as multiplexing.” Pet. 24 (citing Ex. 1003, 4:34–38). Patent Owner does not disagree other than to argue that no claim term requires construction. The ’399 patent states: An indexing site is a nucleic acid sequence that acts as an index for multiple polynucleotide samples, thus allowing for the samples to be pooled together into a single sequencing run, which is known as multiplexing. Ex. 1003, 4:34–38. We understand this passage of the ’399 patent to provide a definition for “indexing site,” and we construe the term in accordance therewith. 2. “indexing primer binding site” Petitioner argues that the ’399 patent defines “indexing primer binding site” as the binding site for a primer used to read the indexing site/sample index, specifically, “a nucleotide sequence for binding a primer for an indexing site.” Pet. 24 (citing Ex. 1003, 4:33–34). Patent Owner does not disagree other than to argue that no claim term requires construction. The ’399 patent states: “An indexing primer binding site is a nucleotide sequence for binding a primer for an indexing site.” Ex. 1003, definition for “indexing primer binding site,” and we construe the term in accordance therewith. 3. “identifier site” Petitioner argues that the ’399 patent defines “identifier site” as a molecular tag attached to fragments prior to amplification, specifically, “a nucleic acid sequence that comprises random bases and is used to identify duplicate sequencing reads.” Pet. 25 (citing Ex. 1003, 4:43-45). Petitioner argues that an “identifier site” “can be designed as a set of sequences, or it can be semi-random, or it can be completely random.” Id. (citing Ex. 1003, 4:49–51). Petitioner argues that an “identifier site” can also “be a fixed length, or it can be a variable length.” Id. (citing Ex. 1003, 4:51–54). Patent Owner does not disagree other than to argue that no claim term requires construction. The ’399 patent states: “An identifier site is a nucleic acid sequence that comprises random bases and is used to identify duplicate sequencing reads.” Ex. 1003, 4:43–45. We understand this passage of the ’399 patent to provide a definition for “identifier site,” and we construe the term in accordance therewith. 4. “target sequence primer binding site” Petitioner argues that the ’399 patent defines “target sequence primer binding site” as a binding site for a primer used to read the fragment sequence, specifically, a “nucleotide sequence for binding a primer for a target sequence.” Pet. 25 (citing Ex. 1003, 4:62–65). Petitioner also argues that the ’399 patent expressly discloses that this site can be a standard Illumina sequence compatible with an Illumina primer for an SBS reaction to read the DNA fragment. Id. (citing Ex. 1003, 16:48–51 & SEQ ID No. 3). requires construction. The ’399 patent states: “A target sequence primer binding site nucleotide sequence for binding a primer for a target sequence.” Ex. 1003, 4:62–63. The ’399 patent appears to have a typographical error at this juncture in the Specification because the quoted text is missing a verb (e.g., “is”) and is therefore an incomplete sentence. Based on the context of the surrounding parts of the Specification, we infer that the ’399 patent intended to define “target sequence primer binding site” as a “nucleotide sequence for binding a primer for a target sequence.”” slip op. at 11

    • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingPreamble not limitingMixed

      “In general, a preamble limits the invention if it recites essential structure or steps, or if it is necessary to give life, meaning, and vitality to the claim.” Catalina Mktg. Int'l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quotations omitted) (quoting Pitney Bowes v. Hewlett- Packard Company, 182 F.3d 1298, 1305 (Fed. Cir. 1999)). “Conversely, a preamble is not limiting where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.” Id. (citations omitted). “[T]he rule against giving invention-defining effect to intended-use preamble language reflects . . . the ‘well settled’ fundamental principle ‘that the recitation of a new intended use for an old product does not make a claim to that old product patentable.”’ Arctic Cat Inc. v. GEP Power Prods., Inc., 919 F.3d 1320, 1328 (Fed. Cir. 2019) (quoting In re Schreiber, 128 F.3d 1473, 1477 (Fed. Cir. 1997)). On the current record, we determine that the recitation of “a DOCSIS Provisioning Of EPON (DPOE) system” in the preamble of claim 1 is limiting because it provides the antecedent basis for the term “the DPOE system” in body of claim 1 (e.g., limitation 1a). We, however, have not received specific arguments from the parties as to why the entire preamble of claim 1 would be limiting based on the antecedent basis provided by “a DOCSIS Provisioning Of EPON (DPOE) system.” Further, as discussed above, Patent Owner does not provide any explanation of or support for its assertion that the preambles of claims 1 and 6 serve to define the invention that is claimed and are not simply a description of the prior art. Prelim. Resp. 22. Because we do not need to resolve the issue of whether the entire preamble of claim 1 is limiting to decide whether to institute inter partes review, we will wait for further briefing from the parties before deciding whether the entire preamble of claim 1 is limiting. For claim 6, we determine that the recitation of “a DOCSIS Provisioning Of EPON (DPOE) system” in the preamble is not limiting because it does not provide the antecedent basis for any term in the body of claim 6. As mentioned, limitation 6a recites “a DPoE system,” rather than the DPOE system. Further, as discussed above, Patent Owner does not provide any explanation of or support for its assertion that the preambles of claims 1 and 6 serve to define the invention that is claimed and are not simply a description of the prior art. We do not independently see such support in the record. Thus, for this Decision, we determine that the preamble of claim 6 is not limiting. Patent Owner argues that the preamble of claim 4 is limiting. Prelim. Resp. 23 (“the preamble is limiting in all the independent claims.”). For this Decision, as set forth in Sections III.A.6.a and III.C.3 below, we do not need to determine whether the preamble of claim 4 is limiting in light of Petitioner’s showings. slip op. at 16

      “At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments. Patent Owner does not cite to evidence, such as expert testimony, to support its implied argument that Olson’s measured current is “fundamentally different” from the current received by the primary coil. See Prelim. Resp. 31–32. Petitioner’s declarant, Dr. Woods, on the other hand, testifies, inter alia, that “[t]he ‘[c]urrent measured by current measure block 226 is used in the calculation of power, which as depicted in FIG. 14, measures the ‘power in’ provided to transmit block 214/primary coil 54.” Ex. 1003 ¶ 37 (citing Ex. 1004 ¶¶ 74–75, Fig. 14) (first alteration added); see also, e.g., id. ¶ 42 (Dr. Woods testifying that the measured current to the power supply “is the current driving the external antenna 52, via the transmit block 214 and to the primary coil 54.” (citing Ex. 1004 ¶¶ 74–75, 112, Fig. 14)). Paragraph 75 of Olson, cited in support of that testimony, provides: “The power in is gauged by the power generated by charging unit 50 and is determined by multiplying the voltage of the internal voltage of charging unit 50, e.g., the voltage of a battery or batteries internal to charging unit 50, by the current driving external antenna 52.” Ex. 1004 ¶ 75 (emphasis added). We note that external antenna 52 includes primary coil 54. See, e.g., Fig. 14. Dr. Woods’ testimony is, at this stage, unrebutted. Patent Owner also argues that “Petitioner fails to provide any evidence regarding the function of Olson’s microprocessor 212 in relation to measuring input power,” and that, “[w]hile Olson describes a power calculation in paragraph [0075], Olson does not describe this power calculation as performed by microprocessor 212.” Prelim. Resp. 32 (citing Pet. 16; Ex. 1004 ¶ 72) (first alteration added). At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments regarding the microprocessor. Although Patent Owner does not bear the burden to show patentability, we observe that Patent Owner does not suggest that there is another component in Olson’s external charging device that might perform the admittedly-disclosed power calculation. See Prelim. Resp. 32–33. Dr. Woods testifies that microprocessor 212 receives the measured current and the input voltage of the charging device, and, from those values, calculates power in. See Ex. 1003 ¶¶ 43–44 (citing, inter alia, Ex. 1004 ¶¶ 71–78, Fig. 14); see also Ex. 1004 ¶ 74, Fig. 14 (Olson stating that “[c]urrent measured by current measure block 226 is used in the calculation of power in along with the voltage of batteries 160,” and Figure 14 depicting the signal from measure block 226 as an input to microprocessor 212).

To teach this limitation, Petitioner relies on disclosures from RFC 4601 and RFC 11127 purporting to show that communications to a multicast group can be drawn from different sources. Pet. 28–31.

      “Upon consideration of the parties’ arguments and for the reasons explained below, we agree with Petitioner that Patent Owner’s additional requirement of evaluating the calibration data to determine the boundaries of the area represented by a grid point should not be included in the construction of either “grid point” or “non-uniform grid point.” Instead, based on the full record, we discern no reason to alter our prior construction of “grid point” as “a point associated with representative calibration data for an area” and maintain that construction for this Final Written Decision for the following reasons. First, the construction of “grid point” we adopt here is supported by the Specification of the ’358 patent. Namely, the ’358 patent discloses that “[i]n general, a non-uniform grid point (NUG) may represent the signal characteristics and/or calibration data over a given region,” and “NUGs represent an area of collected calibration data.”9 Ex. 1001, 3:57–67. The district court identified the second quoted passage, which is identically recited in the ’104 patent (see Ex. 1018, 3:50–60) as “provid[ing] a clear indication of the meaning of ‘grid point.’” Ex. 1028, 19 (emphasis added). We agree with the district court’s analysis.

Patent Owner’s assertion that the ’379 provisional application and the ’784 patent both describe evaluating the statistical similarities of calibration data (PO Resp. 10, 20) also fails to provide a sufficient reason to import a requirement to evaluate the calibration data into the construction of “grid point” or “non-uniform grid point.” Similarly, Patent Owner’s assertion that is “of great importance” because it is fundamental to generating the grid points is unpersuasive.

      “The evidence supports that Petitioner has sufficiently demonstrated that Spain teaches “generating one or more sets of grid points for said calibration data,” as recited in limitation [1.2]. Spain states that: In another embodiment, the database is built by taking fingerprint measurements at predetermined locations and using intelligent algorithms that interpolate the fingerprints at all locations in between the sampled locations. Ex. 1006 ¶ 101. Relevant to this disclosure, Mr. Williams testifies that “Spain discloses generation of sets of grid points wherein each set includes newly interpolated grid points” because “the two grid points used to interpolate an additional grid point or points and the generated additional grid point or points are collectively a generated ‘set’ of grid points (i.e., a ‘set’ which includes the two calibrated grid points and the associated interpolated grid points).” Ex. 1008 ¶¶ 76–77 (citing Ex. 1006 ¶¶ 54, 55, 101). It is not disputed that Spain’s “fingerprints” are calibration data having characterizing parameters, such as observed signal strength, observed at calibration points. See Ex. 1006 ¶ 35. We find that this evidence demonstrates that Spain discloses generating one or more grid points, where the grid points are associated with calibration data.10 Accordingly, the evidence provides support that Spain’s interpolation of fingerprints at different locations discloses generation of one or more sets of grid points, where the grid points are associated with calibration data. Spain also discloses that: . . . the fingerprint corresponds not to one exact spot on the surface of the earth, but instead to a small area.

      “Thus, “grid points” and “calibration points” in the ’494 patent are distinct elements that can overlap. Specifically, a “grid point” is a point associated with representative calibration data for an area, and a “calibration point” is a point at which calibration data is collected. These points can occupy the same physical location (i.e., the same longitude/latitude coordinates) but still be a “grid point” and a “calibration point.” For these reasons, we are not persuaded that the overlap between “grid points” and “calibration points” in Shkedi undermines Petitioner’s position and evidentiary showing.
